No one uses Boot.
The choice is between Leiningen and deps.edn AKA the official Clojure CLI. Personally, I switched to deps.edn back in 2020 and haven't looked back. I like that it's simpler/does less out of the box and I also use the Git dependency feature all the time (you can reference a git sha as a dependency, not just Maven coordinates).
Something like 90% of it is just listing dependencies (the same packages as it's all just Maven anyway) and for the remaining 10% of configuration there's plenty of resources available for both. They can also interop to some extent.
Other ecosystems have it much worse than Clojure in this regard.
